Getting ready for your test
Before your test, tell your doctor or nurse if you are:
- Pregnant or think you may be pregnant
- Allergic to contrast dye or iodine. Be sure to tell your doctor about these allergies before the day of your test. They may have you take medicine the night before and the morning of your test.
- Afraid or anxious in enclosed spaces. You may need medicine to help you relax during your test. This must be arranged before your test begins. If you are given medicines to relax, you will be given special diet instructions and will need a driver to take you home.
Eating and drinking
- If you or your child are going to be sedated by IV medicines or anesthesia, you will have restrictions you must follow on what you can and cannot eat and drink. Talk with your care team.
Medicine
- Take all of your medicines, unless told otherwise by your care team.
Driving
You will need to have someone drive you home after your test if you are given:
- Pre-medicine for an allergy, such as Benadryl
- Medicines to help you relax during the test
Please do not drive for 24 hours after getting sedation.
If you're unable to do any of the prep listed above, you may not be able to have the test or it may need to be rescheduled.
